A 61-year-old man presented with uniocular gradually progressive visual loss, pain in the eye, visual activity of 6/60, markedly constricted visual fields, optic disc edema, retinal pigment epithelial disturbance at the posterior pole, and markedly delayed filling of the choroid on angiography, with a normal fellow eye. He had suffered from recurrent seizures for 15 years, with some evidence of cortical demyelination. Erythrocyte sedimentation rate was elevated. About 5 months after the onset of visual disturbance, evidence of bronchial carcinoma became apparent and he died 6 weeks later. The etiology of his ocular lesions was established only by histopathological evidence of metastases into the optic nerve head and the choroid. Diagnostic problems presented by the ocular findings are discussed.
